32 Claims.

This invention relates to improvements in wringers, especially adapted for use in connection with power-driven washing machines.

One object oi the invention is to provide in a wringer having cooperating power-driven rolls, operating under pressure and adapted to be moved out of operative position with respect to each other to release the rolls from the work, means for automatically displacing one 01' said rolls when the power as applied to rotate the rolls, to bring the rolls into cooperating pressure relation, said means also operating to automatically retract said roll when the operation of the wringer is stopped to facilitate easy restoration of the rolls to operative position.

Another object or the invention is to provide a wringer having cooperating rolls operating under pressure, wherein one the rolls is carried by a movable or swinging frame to permit moving said roll away from the other roll to release the mechanism, and wherein means is further provided for automatically projecting one or said rolls toward the other when the power is applied to rotate said rolls, thereby bringing said rolls into pressing relation with each other, said last named means also restoring said roll to its original position when the pressure is released due to displacement of the movable frame, thereby providing clearance between the rolls to lacilitate moving the frame to and from its operative position.

A more specific object of the invention is to provide a wringer having cooperating rolls, one of which is carried by a iixed frame and the other by a movable irame adapted to be swung to a position to bring the rolls into operative relation and to be displacedirom said operative position to release the pressure between the rolls, a yielding pressure-exerting means for iorcing said rolls toward each other arranged and designed so that the irame may be displaced to one side or the other of centered position without disturbing the adjustment 0! said yielding pressure means, wherein one or said rolls is held in spaced relation to the other roll while the mechanism is idle to provide clearance for said other roll during swinging movement or the frame and wherein said last named roll is automatically projected into operative pressuretransmitting relation with respect to said other roll when the power is applied to rotate said rolls.

Other objects 01 the invention will more clearly appear from the description and claims hereinafter following.

In the drawings, forming a part or this specification:

Fig. 10 is an elevational view 01' a certain arm and cooperating slide of a cam shalt shown in Figs. 1 to 6 inclusive and 8, the cam shaft being shown in vertical section in Fig. 10.

Fig. 11 is a horizontal, sectional view corresgonding substantially to the line |i| I of Fig.

In said drawings, 20 indicates the main or bottom frame oi the wringer and 2| a swinging frame supported for movement with respect to said main irame. A housing 22, forming a part oi the main frame II, contains power-transmitting gear connections, under control of the operator for starting and sioppingrotation oi! the wringer rolls and driving the same in either right or left-hand direction. The housing 22 has a depending sleeve portion I! for mounting the wringer on a washing machine. The gear mechanism in the housing I! is driven by the driving elements 01' the associated washing machine in the usual well known manner. In this connection, it is pointed out that the sleeve ll of the housing 22 telescopes over.the usual vertically arranged hollow standard oi the washing machine having a vertically disposed shalt therein cperatively connected to and rotated by the driving elements of said washing machine. This shaft is coupled to the gearing in the housing 22 in any well known manner to impart rotary movement to said gearing.

The swinging frame 2| of the wringer is pivotally supported on inwardly projecting trunnions 24-24 on upstanding arms 25-25 at opposite sides of the main frame 23, the frame 2| being provided with fixed bearing sleeves 23-23 in which the trunnions are journeled.

The top and bottom rolls of the wringer. which are indicated by 21 and 23, are carried respectively by said swinging frame 2| and main frame 23. The roll 21 is fixed on a shaft 29, which projects from opposite ends of the roll and is rotatably journaled in bearing blocks 33-33. The bearing blocks 33-33 are suspended in the frame 2| in such a manner that downward movement of the same and the roll 21 supported thereby is limited, and that upward movement thereof is yieldingly opposed. The mechanism for thus mounting the bearing blocks 33-33 and the roll 21 forms the subject matter of my copending application, Serial No. 54,284, filed December 13, 1935, now Patent No. 2,198,462 granted April 23, 1940 and is fully described therein. Briefly, this mechanism comprises links 3|-3| pivotally connected at their lower ends to the bearing blocks 33-33; triangular lever plates 32-32, to the lower corners of which the upper ends of the links 3|-3| are pivoted; pivot members 33-33 on which the lever plates swing, said pivot members being fixed to the frame 2 followers 34-34 connected to the inner lower corners of the lever plates 32-32 by links 35-35; and springs 33-33 interposed between the followers 34-34 and spring abutments |31-|31. As will be seen, the spring followers 34-34 engage with each other, thereby limiting movement thereof, and through the links 35-35, lever plates 32-32, and links 3|-3| limiting downward displacement of the bearing, blocks 33-33 and the roll 21 carried thereby. Inasmuch as the springs 35-33 yieldingly resist separation of the followers 34-34,

these springs yieldingly oppose upward movement of the rolls through the connections formed by the links 35-35, levers 32-32, and links 3 |-3l with the bearing blocks 33-33 of said roll 21.

The swinging frame 2| is normally held in centered position with respect to the main frame 23 by latch means comprising latch plates 31-31 on the frame 2| cooperating with keepers 33-33 fixed to the side arms of the main frame 23. The latch plates 31-31 are guided for vertical movement in guideways 39-39 in the frame 2| and are forced outwardly or downwardly by springs "-43 seated in pockets 4|-4| in said frame 2| to yieldingly engage with seats 42-42 of the keepers 33-33. The latch plates 31-31 are normally locked in projected position in engagement with the seats 42-42 of the keepers 33-33 by releasable locking means including a slide bar 43 engaging the upper ends of the plates. The means for locking the swinging frame 2| in centered position, comprising the latch plates 31-31, the keepers 33-33, and the releasable locking means including the slide bar 43, forms the subject matter of my copending application, Serial No. 54,282, filed December 13, 1935, and is fully described therein, and therefore needs no further detailed description in connection with the present application. However, it might be pointed out that, as disclosed in said last named copending application, the means for releasing the latch means is designed to be actuated at will by the operator or automatically actuated when the wringer rolls become jammed, so that the frame 2| may be swung to either side of centered position to effect separation of the rolls to release the same. As further described in said last named copending application, provision is also made for automatically stopping rotation of the rolls by means actuated through displacement of the frame to either side of its centered position.

The main frame 23 has a troughlike portion 44, which contains the bottom roll 28. At opposite ends of the trough 44, supports 45-45 are provided, which are fixed to the main frame 23. Each support 45 forms a part of a casting 46 fixed to the corresponding side wall of the frame 23. The lower ends of the supports 45-45 abut flat bottom wall portions 41-41 provided at opposite ends of the trough 44, as most clearly shown in Fig. 2. Supporting brackets 48-43 are secured to the bottom wall portions 41-41 of the trough 44, said brackets having depending flanges 43-43 provided with openings in which a cam shaft 53, hereinafter more fully described, is journaied. As most clearly shown in Figs. 2 and 8,. the brackets 43-43 are held in place by screws extending through horizontal top flanges on the brackets and through the bottom wall sections 41-41 of the trough 44 into the supports 45-45. Each support 45 has a vertically arranged guideway 5| in which is mounted for vertical movement a slide 52. Each slide 52 has 9. depending stem portion 53 loosely extending through aligned openings in the bottom of the support 45, the bottom wall of the trough 44, and the horizontal flange of the corresponding bracket 43. The bottom end of the stem of each slide 52 is tapered, as shown in Figs. 2, 5, 6, and 8, and is provided with a rounded extremity adapted to cooperate with a cam member 54 fixed to the corresponding end of the cam shaft 53. Each slide 52 has a curved seat 55.

As shown in Fig. 1, rocking guard members 53-53 are provided at opposite sides of the main frame 23, which serve to guide and direct the material operated on through the wringer. Each guard member 53 is provided with a sleevelike bearing section 51, which is supported in the seat 55 of the corresponding slide 52.

The bottom roll 23 is mounted on and fixed to a shaft 53, which projects from opposite ends of the roll and is rotatably Journaled in the bearing bushings in the sleeves 51-51 of the guard members 53-53. As shown most clearly in Fig. 1, the ends of the shaft53 project beyond the outer ends of the corresponding sleeves 51- 51. The bottom roll 23 is driven by the gearing contained in the housing 22 of the main frame 23, the hub portion of the driven gear member of said gearing being shown in Fig. 1 and indicated by 53. Said hub portion 59 is provided with a central pocket 33 having a driving lug 3| of angular cross section projecting from the inner wall thereof. The right-hand end of the shaft 53 of the roll 23 is operatlvely connected to the lug 3| by means of a. coupling sleeve 32, which is telescoped over said lug 3| and a portion 33 of square cross section at the corresponding end of the shaft 53, the interior of the coupling sleeve 32 being of angular cross section to correspond with the lug 3| and the end portion 53 of the shaft 53, thereby forming a driving connection between the shaft and the hub 55 of the gear hereinbefore referred to.

The coupling sleeve 52 loosely fits the lug GI and the portion 55 of the shaft 58 so as to form a flexible connection between these parts, which permits the roll 28 to be raised or lowered while being driven through the driving gear mechanism of the wringer. The two rolls 21 and 25 are in ergeared so that rotation is imparted from the roll 28 to the roll 21. Gears 54-84 and 54-54 are provided for this purpose, said gears being fixed respectively to the shafts 28 of the top roll 21 and 58 o! the bottom roll 28.

An arm 55 is fixedly mounted on the projecting end of the shaft 58 at the left-hand side of the mechanism, as shown in Fig. 1. said arm rotating with the roll 28 and actuating the cam shaft 58, as hereinafter more fully described. As shown most clearly in Figs. 1 to 6 inclusive and 8, thearm 55 is provided with a laterally enlarged head portion 65 at the outer end thereof having rounded opposite end portions 51-51.

As shown most clearly in Fig. l, the cam shaft 58 has a radially extending arm 68 fixed to the left-hand end portion thereof. A slide block 69 is movably mounted on said arm 58. The slide block 69 is provided with an upstanding section 18 projecting beyond the outer end of the arm 55. On the side of the slide adjacent to the lefthand end of the shaft 58, as shown in Fig. 1, a lateral enlargement 1| is provided, which is of substantially the shape shown most clearly in Fig. 10. The enlargement 11 forms a head member having rounded portions 12-12 at opposite sides thereof. The enlargement or head 1| is in alignment with the arm 55 at the end of the shaft 58 of the roll 28 so that when the parts are in the position shown in Figs, 1, 2, and 8, the head II will be in the path of movement of the head portion 85 of the arm 55. A tension spring 13 connected at the lower end to a pin 14 fixed in the outer end of the section 18 the slide block 59 and anchored at its upper end to a hook-shaped lug on the corresponding side wall of the main frame 24 serves to exert an upward pull on said slide block 58. A pin extending through the outer end of the arm 85 limits the outward movement of the slide block 89 with respect to said arm. The spring 12 exerts a pull at all times to restore the arm 88 to the central position shown in Figs. 2 and 8 whenever the arm is swung to either side of said centered position.

The cam members 54-54 which are disposed at opposite end .portions of thecam shaft 58,.

are respectively arranged immediately below the downwardly extending stems 58-53 of the slides 52-52 which support the bottom roll 28. Each cam member 54 has a hub section, which is secured to the shaft 55 by means of a pin or any other equivalent securing element and is provided with a radially extending, fan-shaped, cam plate section 18, which has a low cam portion 11 at the center thereof and high cam portions 18-18 at opposite sides of said low cam portion. As shown most clearly in Figs. 2, 5, 6. and 8, the high cam portions 18-15 and said low cam portion 11 are provided with seats or notches 19-19-18, which cooperate with the rounded lower extremity of the stem 58 of the corresponding slide 52. The notched arrangement of the cam members 54-54 by cooperation with the ends of the stems 53-53 of the slides 52-52 provides for holding the cam members 54-54 in adjusted position as long as pressure is exerted on the bottom roll 28 of the wringer.

When the cam members 54-54 are in the position shown in Figs. 1, 2, and 8, with the low portions 01' the cam. members in engagement with the lower ends of the stems 53-53 of the slides 52-52, the bottom roll 28 is supported in spaced relation with respect to the top roll 21, This is the condition of the parts after the pressure between said rolls has been removed. Assuming that the operation of the wringer is started and rotation imparted to the roll 28, the arm 65 which rotates with said roll will engage the head portion 1| of the slide block 58 on the arm 58 of the cam shaft 58, thereby swinging said arm to one side or the other of the centered position, depending upon the direction of rotation of the roll 25. As shown in Fig. 5. when the roll 28 is rotated in a clockwise direction, the slide block 58, together with the arm 58, is swung to the left, thereby turning the cam shaft 58 and bringing the cam members 54-54 to the position shown in Fig. 5 with the high cam portions 18-18 thereof in engagement with the stems 53-53 of the slides 52-52, thereby lifting the slides together with the roll 28 and bringing the bottom roll 28 in pressure-exerting relation with the top roll 21. In Fig. 6, the roll 28 is shown rotated in a contraclockwise direction, thereby swinging the arm 58 in a reverse direction to that shown in Fig. 5 and rotating the cam members to bring the other high cam portions 18-18 into operative engagement with the slides 52-52 to raise the latter and lift the roll 28, as hereinbefore described. As will be seen, when the m 58 is swung to either side of the centered position, as shown in Figs. 5 and 6, the spring 13 will be tensioned, thereby exerting a pull on said arm tending to return the same to the centered position. However, as long as pressure is exerted between the rolls 21 and 28, the rounded lower ends oi the stems 53-53 of the slides 52-52 will remain securely seated in the notches of the high cam portions 18-18, thereby locking the cam shaft 50 and the arm 68 thereof against movement. When this pressure is removed through separation of the top roll 21 from the bottom roll 28, the force of the spring 13 is suflicient to effect disengagement of the rounded end portions of the stems 53-53 of the slides 52-52 from the notches 19-19 of the high cam portions 18-18 of the cam members 54-54 and swing the arm 68 to the centered position shown in Figs. 2 and 8. thereby bringing the low cam portions 11-11 of the cam members 54-54 into position beneath the stems 53-53 of the slides 52-52, thus lowering the slides and the roll 28 carried thereby to the position shown in Figs. 1, 2, and 8. Should the arm not be clear of the path of swinging movement of the head 1| of the slide 65 of the arm 58, the rounded portions of the heads 65 and 1| will ride over each other, the yielding connection provided by the spring 13 permitting inward sliding movement of the slide 5! on the arm 68. It is further pointed out that should the arm 65 be in a depending position when the roll 28 is being lowered. the arm 58, together with the slide 59, will strike the arm 55 and move it aside, the free condition of the roll 28 permitting this action. In the operation of my improved wringer, the pressure between the rolls 21 and 28 is removed by separating the rolls through swinging movement of the frame to either side of the centered position, as shown in full lines and indicated by dotted lines in Fig. 8. This removal of the pressure renders operative the mechanism for restoring the cam members 54-54 to centered position, as hereinbefore described.

In the normal operation of the wringer, the rolls 2'! and 28 are in pressureexerting relation, as shown in Figs, 1 5, 6, and 7. In case it is found desirable, or necessary in an emergency, to release the rolls of the wringer from operative engagement with each other, the latch mechanism comprising the plates Iii-31 and the keepers 38-38 of the frames 2! and 20 respectively is released by the operator in the manner described in my copending applications hereinbefore referred to, thereby permitting the swinging irame 2| to be swung to either side of the centered position through the reactive force between the rotating gears B L-64 and -64 of the rolls 2! and 2B. As has also been pointed out in said copending applications, the locking means is also released automatically through jamming of the wringer rolls. As will be obvious, the frame 2! when unlocked from the frame 20 is free to be swung to either side of the centered position by the operator. The parts of the wringcr are reset by manually swinging the frame 2| from either side of the centered position to said centered position, thereby bringing the latch plates 31-31 into latching engagement with the keepers 3B-38. Inasmuch as the bottom roll 2E has been previously lowered to the position. shown in Figs. 1, 2, and 8, thereby providing clearance for the top roll 21, restoration of the frame 2! to centered position may be easily efiected with very little effort as the rolls are not brought into pressure-exerting relation until the bottom roll 28 is again raised by power being applied to rotate the same.

From the preceding description taken in connection with the drawings, it will be seen that I have provided a wringer, the rolls of which may be released from operative pressure engagement with each other without disturbing adjustment of the means which controls the pressure between said rolls while operating on an article, and the parts of which may also be easily restored to normal operative position without disturbing said adjustment.

I have herein shown and described what I now consider the preferred manner of carrying out my invention, but the same is merely illustrative and I contemplate all changes and modifications that come within the scope of the claims appended hereto.

In a wringer, the combination with a pair of cooperating rolls; of means for yieldingly forcing one of said rolls toward the other roll and limiting the movement of said yieldingly forced roll toward said other roll; means for holding said other roll in operative position with said yieldingly forced roll during operation of the wringer; main and auxiliary frames carrying said rolls respectively; means movably supporting one of said frames with respect to the other frame; releasable means for locking said frames together with the rolls in cooperative relation, said last named means when released permitting movement of said movable frame away from the other frame to separate said rolls; and means rendered operative through separation of said rolls upon movement of said movable frame away from the other frame for withdrawing said holding means to release said other roll from operative position.

22. In a wringer, the combination with a pair of cooperating rolls; of means for projecting one of said rolls against the other roll to bring the rolls into cooperative pressure engagement with each other; yielding pressure-exerting means acting on said other roll and yieldingly opposing displacement thereof by said projected roll; and means for actuating said first named means to retract said projected roll, said actuating means being held inoperative by the pressure exerted between said rolls and becoming operative when said pressure is released.

23. In a wringer, the combination with a pair of cooperating rolls; of displaceable means for supporting one of said rolls in operative relation with respect to the other roll; releasable means for locking said supporting means in operative position; pressure-exerting means carried by said displaceable means for maintaining the roll supported by said displaceable means yieldingly projected to engage with said other roll; and means for retracting said other roll from operative engagement with the yieldingly projected roll to provide clearance between said rolls to permit free movement of said supporting means to locked position.

24. In a wringer, the combination with a pair of cooperating rolls; of means for yieldingly forcing one of said rolls toward the other and limiting movement of said yieldingly forced roll toward said other roll; movable means for advancing and retracting said other roll to and from operative pressure-exerting position with respect to said yieldingly forced roll; main and auxiliary frames carrying said rolls respectively; means movably supporting one ofsaid frames with respect to the other frame to permit movement of the roll carried by said movable frame away from operative position with respect to the roll carried by the other frame and remove the pressure between said rolls; yielding means for holding said movable means and the roll associated therewith in retracted position to provide clearance between said rolls during movement of said movable frame to return the roll carried thereby to operative position; and means actuated by rotation of said rolls for actuating said movable means to advance said other roll to operative pressure-exerting relation with respect to said yieldingly forced roll.

25. In a wringer, the combination with a pair of cooperating rolls; of dispiaceable means for supporting one of said rolls, said displaceable means being movable to and away from a position in which said rolls cooperate; safety release means for maintaining said displaceable means in a position in which said rolls cooperate; advancing and retracting means for forcing the other roll into operative engagement with the roll carried by said displaceable means and for separating said rolls to provide clearance therebetween during movement of said displace able means away from a position in which said rolls cooperate; and means for maintaining the roll which is carried by said displaceable means under yielding pressure while operatively engaged by said other roll.

26. In a clothes wringer the combination of a lower frame, a relatively movable upper frame, mechanism including a quickly releasable safety latch for releasably securing said upper frame to the lower frame, an upper roll, a spring mounted in the upper frame for stressing said upper roll downwardly, a lower roll mounted in the lower frame, and quick throw lever mechanism for raising said lower roll into pressure relationship with the upper roll or lowering it away from such pressure relationship.

27. In a clothes wringer, a pair of cooperative rolls, a lower frame, a relatively movable upper frame, means releasably holding said frames against relative movement, resilient means supported on the upper frame normally urging the upper roll into pressure contact with the lower roll, and dual position cam means supporting the lower roll and operable to quickly drop the lower roll from pressure relationship or raise the lower roll into pressure contact with the upper roll.

28. In a clothes wringer, a frame including relatively movable upper and lower frame sections, quick release means for releasably conmeeting said frame sections against relative movement, cooperative wringer rolls mounted on said frame, spring means urging said rolls into pressure relationship. roll bearings slidably mounted in the lower frame, a cam shaft rotatably mounted in and extending longitudinally of the lower frame, cams rigidly secured and rotatable with said shaft and directly supporting the lower roll bearings, and means attached to said shaft and operable to release roll pressure, or restore roll pressure while said frame sections are operatively connected by said quick release means.

29. In a clothes wringer the combination of a lower frame, an upper frame, an upper roll mounted in bearings supported in said upper frame by a pressure spring and pressure adjustmentscrew, means to releasably attach the upper frame to the lower frame, a lower roll mounted in the lower frame on quick throw cams actuated by a cam shaft, and a lever mounted on the end of said cam shaft whereby the lower roll may be lowered away from or raised into pressure contact with the upper roll.

30. In a clothes wringer the combination of a lower frame, an upper frame releasably attached to the lower frame by mechanism including a quickly releasable safety latch, an upper roll stressed downwardly by a spring mounted in the upper frame, and a lower roll mounted in the lower frame on quick throw lever mechanism whereby said roll may be raised into pressure relationship with the upper roll or lowered away from such pressure relationship.

31. In a clothes wringer, a lower frame, an upper frame releasably mounted on the lower frame, an adjustment screw in the upper frame, a pressure spring supported by said screw, roll bearings supported by the pressure spring, an upper roll mounted insaid bearings, a quick throw cam shaft supported in and extending through the lower frame, roll bearings supported on said cams, a lower roll mounted in said bearings, and a lever on the end of said cam shaft whereby the lower roll may be raised for pressure contact with the upper roll or lowered from such pressure contact to permit easy attachment of the upper frame with the lower frame and adjustment of the spring pressure.

32. In a clothes wringer, a lower frame, an upper frame releasably attached to the lower frame, an upper roll adjustably spring mounted on the upper frame, a lower roll mounted in bearings movable vertically in the lower frame, and quick throw cam means supporting said bearings operable by'a lever whereby the lower roll may be raised for pressure contact with the upper roll or lowered to separate the rolls to permit easy pressure-free attachment of the upper frame and roll pressure adjustment.
